-
HDT is a compact data structure and binary serialization format for RDF that keeps big datasets compressed to save space while maintaining search and browse operations without prior decompression.
-
There is a GUI Desktop Tool to work with HDT. This tool allows us to convert RDF files to HDT format. I tried to transform a TTL file with 10M triples to an HDT file and it just took a few minutes.
-
In the official website of HDT they provide some big datasets as Wikidata or DBPedia in HDT format already,
-
Apache Jena provides a HDT library to work with it.
-
It´s said that is posible to deploy a SPARQL Endpoint of HDT files using Jena Fuseki. However, I tried to upload an HDT file on one of my fuseki instances and it pointed an syntax error. There is a manual for doing that which says that you can do it in a few minutes but it doesn´t seem that easy. Some of the example file links are down. Also, there is a repo for the same porpouse but after compiling I get this error when I try to run the server:
Play with HDT, try to convert some RDFs to HDT format and query them. Please add some instructions and the flow flowed. Add also, if possible, some feedback about it.
